STOP AND WASTE COCK.

SPECIFICATION forming part of Letters Fatent No. 613,052, dated October 25, 1898.

Application filed August 30, 1897. Serial No. 650,016. (No model.)

T0 all whom it may concern:

Be it known that We, MICHAEL F. BARRETT, JOSEPH H. LYoNs, and PATRICK J. F. TUMNEY, of Cleveland, Cuyahoga county, Ohio, have invented certain new and useful Improvements in Stop and Vaste Cocks; and we do hereby declare the following to be a full, clear, and eX- act description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.

Our invention relates to improvements in stop and waste cocks. v The object is to render the cock reversible top for bottom, or vice versa, and to adequately and positively drain the pipe to be drained without necessitating the opening of the cock or valve with which the said pipe is provided and without requiring the employment of a costly vent device.

Another object of the invention is to simplify the means whereby the cock is rendered right-handed and left-handed and whereby the said means can be adjusted as required in changing from a right-hand position to a left-hand position, or vice versa, without necessitating the removal of any part.

With these objects in view our invention consists in certain features of construction and combinations of parts hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure I is a front side elevation of a stop and waste cock embodying our invention and shows the same interposed between a water-supply pipe and a pipe to be supplied with water. Fig. II is a rear side elevation of the saine in central vertical section. Fig. III is a top plan of the saine. sitionV of the plug reversed relative to the position of the plug in the preceding figures. Fig.V.is a transverse section on line V V, Fig.I.

Referring to the drawings, A designates the casing of a cock that is provided with a pas-` sage-way A', extending longitudinally therethrough.

B represents the tapering plug, that is suitably seated in a corresponding chamber in and centrally of the said casing and arranged transversely of the aforesaid passage-Way. Plug B has a lateral port b extending there- Fig. IV is a top plan showing the po-` through and arranged to enable it in the open position of the plug to establish continuity in the passage-way A of the valve-casing. One of the side walls of port b is provided with two holes b b', that extend from said port to the peripheral surface of the plug and are arranged at the upper end and lower end, respectively, of the said port and far enough apart to connect with the top and bottom, respectively, of the aforesaid passageway A when the plug is in its draining position, and of course the said holes b b' communicate with the one or the other end of the said passage-way upon turning the plug upon its axis in the direction and to the extent required. The lower hole b constitutes the waste-hole of the plug, and the upper hole b forms a vent for admitting to the upper end of the plugs port the atmospheric pressure required to completely drain the pipe supplied with water upon closing the cock or valve (not shown) with which vthe said pipe is provided.

The valve-casing is provided with two lateral parts a a in open relation with the eX- ternal atmosphere and adapted to communi- Acate with the upper end and lower end, re-

spectively, of the plugs port b. The upper hole a constitutes a vent that admits atmos pheric pressure to the plugs port through the plugs vent-hole when the plug is in its draining position, and the lower port a forms a Waste-hole that is in open relation with the plugs port through the latters waste-hole when the plug is in its draining position. The vent-hole and the waste-hole of the valve-casing are located, preferably, farther apart than the vent-hole and waste-hole of the plug, and consequently the plugs port is enlarged upwardly and downwardly to accommodate the said arrangement of the venthole and waste-hole of the casing.

Those skilled in the art will understand that one end of the valve-casing is adapted to connect with the supply-pipe C and the other end with the pipe C to be supplied and that the device is considered right-handed or left-handed, according as the right-hand end or the left-hand end of the passage-way through the valve-casing is the discharging end of the said passage-Way.

IOO

In Figs. I, II, and III the supply-pipe is connected with the left-hand end of the valve casing, and the pipe to vbe supplied is connected with the casings right-hand end. In the plugs draining position, as illustrated in the said figures, the plugs waste-hole communicates with the right-hand end of the passage-way through the said casing, and the plugs port is in open relation with the venthole and waste-hole in the forward side of the casing. Hence the plug and connected parts, as shown in the said figures, are arranged to drainfrom the casings right-hand end, and consequently have the arrangement required to constitute it a right-handed device.

In Fig. IV the parts are shown in the position required to drain from the left-hand end of the casing, and consequently in this iigure the supply-pipe is attached to the righthand end of the casing, and the pipe to be supplied is connected with the casings lefthand end.

The tapering plug at its larger end extends outside of the valve-casing and is provided at the outer side of the casing with a portion B, projecting beyond and arranged in line with the plug proper and terminating at its inner end in an annular flange B2. A collar D is mounted upon member B' of the plug kand is adjustable circumferentially of the plug. Preferably the external surface of member B is annular and slightly conical, and the engaging internalsurface of collar D is correspondingly conical. Collar D is provided externally with a stop-forming lug d, that extends inwardly beyond the inner end of the collar between two stop-forming lugs ct' a2, formed upon the valve casing a suitable distance apart at the inner end of the said collar. The collar is adjustably secured to the plugs member B by a screw E, that extends through a correspondingly-threaded hole D in the collar at the upper end of the lug d into a correspond-inglythreaded hole B4, formed in the plug, and the said member B of the plug is provided with two holes B4 B4, arranged at right angles to each other. The arrangement of parts is such that when the plug is in the position required to drain from the right-hand side the stop-forming lug upon the collar engages the stop-forming lug cl upon the valve casing and the collar securing screw engages one of the threaded holes in the plug, as shown in Figs. I, II, III, and V; that when the plug is in the position required to drain from the left-hand side the said screw engages the other threaded hole in the plug and the stop forming lug upon the collar abuts the stop-forming lug Ca2 upon the valve-casing, as shown in Fig. IV, and that when the plug is in the position shown in Figs. I, II, and III a quartereturn of the plug to the left shall open the plug and interrupt communication between the vent-holes of the plug and valve-casing and between the waste-holes of the plug and casing, and that when the plug is in the position shown in Fig. IV a quarter-turn to the right is required to attain the same result. The handle G for actuating the plug is provided at its inner end with an angular lug g for engaging a correspondingly shaped hole B3, formed in the plugs member BC The handle-lug g has preferably a notch or recess g engaged by screw E when the parts are properly assembled.

It is obvious that by our improved construction the device is reversible top for bottom, and vice Versa, and that when the device is reversed the holes in the plug and casing that constituted the vent-holes in the devices previous position form the waste-holes in the reversed position, and that the ventholes in the reversed position were the wasteholes in the previous position.

Our improved device therefore has the following meritorious features: It is reversible top for bottom, or vice versa. It will waste or drain perfectly at all times when it is in its draining position, and neither its collar, that is instrumental in turning the plug from its water-supplying or open position into its draining position, or vice versa, nor any other part need be removed in changing the device from a right-handed one to one that is lefthanded, or vice versa.

l. A stop and waste cock having its valvecasing provided with a passage-way extending therethrough, a plug seated within the casing and arranged transversely of the said passage-way, alateral port formed in the plug and adapted to establish continuity in the said passage-way, two holes formed in the plug and leading from the plugs port to the plugs peripheral surface and arranged far enough apart to communicate with the top and bottom of the aforesaid passage-way in the plugs draining position, and two holes formed in the valve-casing and arranged to connect the upper end and lower end, respectively, ot the plngs port with the external atmosphere when the plug is in its draining position, substantially as set forth.

2. A stop and waste cock having its valvecasing provided with a passage-way extending therethrough, a plug seated within the casing and arranged transversely of the said passage-way, a lateral port formed in the plug and adapted to establish continuity in the said passage-way, two holes formed in the plug and leading from the plugs port to the plugs peripheral surface and arranged far enough apart to communicate with the top and bottom of the aforesaid passage-way in the plugs draining position, and two holes formed in the valve-casing and arranged to connect the upper end and lower end, respectively, of the plugsport with the external atmosphere in the plugs draining position, and the said holes in the valve-casing being lo- IOO IIO

cated farther apart than the aforesaid portconnecting holes in the plug, substantially as set forth.

3. A stop and waste cock having its valvecasing provided with a passage-way extending therethrough, a plug seated Within the casing and arranged transversely of said passage-way, a lateral port formed in the plug,

' two holes formed in the plug and leading from upon and adjustable circumferentially of the v said projecting end of the plug and provided with a screw-threaded hole arranged to register with the one or the other of the said holes in the plug according as the collar is adj usted circumferentially in the direction and to the extent required; a screw engaging the said hole in the collar and the registering hole in the plug, and a stop-forming lug formed upon the collar and extending inwardly between the stop-forming lugs of the valve-casing and the said stops upon the casing being located just far enough apart to limit the sweep of the stop-forming lug upon the collar to the extent required to accommodate the'turning of the plug from a draining position into its open position or vice versa, substantially as shown, for the purpose specified.

4. A stop and waste mechanism comprising a body and plug and a waste-passage through said parts, and an air-vent entering the said body above said waste-passage and discharging into theinside of said body.

5. The stop and waste cock having wastepassages, and an air-vent inlet-passage for veut purposes entering through the body of the cock.

In testimony whereof We sign this specification, in the presence of two witnesses, this 24th day of August, 1897.
